## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agentshelf-twitter-title-extractor-e0b2cd8c -d '<json body>'
```

Example prompt: Can you extract the twitter:title meta tag from this page for me: https://example.com/article?

## When to prefer this

Use this endpoint when you need specifically the twitter:title meta tag extracted from a public webpage or raw HTML, and you want SSRF-safe fetching with a flat per-call cost. Prefer the free sandbox endpoint /v1/sandbox/profile-twitter-title first if available. Choose this over a generic HTML scraper when you only need Twitter card title metadata specifically.

## Known failure modes

- URL is unreachable or returns a non-200 HTTP status
- SSRF protection blocks private/internal IP ranges or localhost URLs
- twitter:title meta tag is absent from the page, returning empty result
- HTML input exceeds 200,000 character limit
- URL shorter than 8 characters or longer than 2048 characters
- Payment of $0.003 USDC not provided or rejected

## How this service works

Call when an agent needs twitter:title extracted from a public page or HTML (SSRF-safe). Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/profile-twitter-title first.

## Output

Returns the extracted value of the twitter:title meta tag found in the specified URL's HTML or in the provided raw HTML string. If the tag is absent, returns null or an empty result.
